Article VIII. LIST OF BATS COLLECTED BY MR. H. 



H. SMITH IN THE SANTA MARTA REGION 



OF COLOMBIA, WITH DESCRIPTIONS 



OF NEW SPECIES. 



By J. A. ALLEN. 



This second paper on the collection of mammals made by Mr. 

 Herbert H. Smith in the Santa Marta region of Colombia, 1 pre- 

 sented to the Museum by Mr. Morris K. Jesup, relates exclu- 

 sively to the Bats, which number about 175 specimens, and are 

 referable to 22 species, of which 3 appear to be hitherto unde- 

 scribed. Of the species here recorded only 7 are included in 

 the collection made by Mr. W. W. Brown, Jr., for Mr. Outram 

 Bangs, in the same general region. 2 Mr. Bangs's list numbers 10 

 species, the 3 not yet sent by Mr. Smith being Vampyrops 

 lineatus (E. Geoff roy), Dermanura quadrivittata Peters, and Uro- 

 dernia planirostris (Spix). In all probability this total of 25 

 species will be considerably extended by the results of Mr. 

 Smith's further work in this region/ 



1. Diphylla ecaudata Spix. One specimen, Cacagualito 

 (altitude 1500 feet), May 26. 



2. Desmodus rufus Wied. Sixteen specimens, Bonda, 

 January, March, June, and July 13 adult and 3 juv. 



These specimens represent two sharply defined color phases, 9 

 being in the rufous phase, like the type of D. rufus Wied, and 7 

 in the gray phase, like the type of D. murinus Wagner. As 

 there are no appreciable differences between the two series except 

 in color, the natural inference is that the species is dichromatic. 



In the rufous phase the color above is dark rufous brown, the 

 hairs basally light yellow ; below pale yellowish brown, the hairs 

 uniform from base to tip, the tips slightly silvery. In the gray 

 phase the color above is blackish brown, the basal half of the 

 hairs grayish white ; below lustrous silvery gray at the surface, 

 the hairs darker (pale brown) basally.
